Abstract

(57) [Summary] (with modifications) [Purpose] Utilize the characteristics of the ratchet handle when tightening and loosening screws using a crab-shaped spanner.
Even in a work environment with a small and limited rotation range, it can be rotated to any angle, making it easy to work even in places where the rotation range of the crab-shaped wrench is narrow, and ensuring safety. [Structure] Instead of conventionally having a crab-eye pin and a handle as one unit, this new design improves workability and safety by making the handle 4 and pin 2 two pieces so that the handle 4 and pin 2 can each be operated at any angle. be.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention is related to the work of tightening and loosening screws using a crab-shaped wrench. , especially contributing to improvements in workability and safety. Concerning cranioid spanners.

0002

[Conventional technology]

The conventional crab-eye spanner has a crab-eye pin 2 and a handle 7 that are integrated, as shown in Fig. 2. structure, and the phase angle between the crab eye pin 2 and the handle 7 is fixed, so the limit It is difficult to work in a place with a narrow rotation range, and it is difficult to work in a place with a narrow rotation range. It was not easy to align the screw 5 with the hole 6. Also, the crab eye pin 2 is in hole 6. The machine fell off and the hand was caught between the open handle 7 and another machine, resulting in an injury. I also saw that. When the crab-eye spanner is turned forcefully, the crab-eye pin 2 will come out of the screw. If it comes off the hole 6, it may damage the area around the hole 6, deform the hole 6, or cause it to become large. This sometimes caused a huge hindrance during the next task.

0003

[Problem that the idea aims to solve]

In the above conventional technology, the phase angle between the crab eye pin 2 and the handle 7 is fixed. , there are many problems with workability and safety. Crab eye pin 2 and handle 7 are integrated structure , the phase angle between the crab eye pin 2 and the handle 7 will be fixed and It was not possible to easily work in a dirty place and to ensure safety.

0004 The purpose of this invention is to use a crab-shaped wrench to tighten and loosen screws. , A work environment with a small and limited rotation range by taking advantage of the characteristics of the ratchet handle 4. However, it can be rotated to any angle, and can be used in places where the rotation range of the crab-shaped wrench is narrow. It is easy to work and also has an infinite rotation range, without having to turn the crab-eye spanner many times. Crab eye that allows you to safely tighten and loosen screws in a short time. It's about providing a spanner.

[0005]

[Means to solve the problem]

The crab-eye spanner of the present invention does not have a structure in which the crab-eye pin 2 and the handle 7 are integrated. In order to freely change the phase angle between the crab-eye pin 2 and the handle 7, the crab-eye pin 2 is With the two-piece structure of the handle 7 and the handle 7, a free phase angle can be obtained. Crab eye pin 2 turns A guide 1 is placed around the screw to prevent it from easily coming out of the hole 6 of the screw 5. Attach the serpentine pin 2 from the screw hole 6 so that it cannot be easily pulled out, and then This solution solves the problems mentioned above.

[0006]

【Example】

An embodiment of the present invention will be described below with reference to FIG.

[0007] The crab-eye spanner according to the present invention has a crab-eye socket 3 with a guide 1 as shown in Figure 1. and ratchet handle 4 were used in combination. Crab eye socket 3 is a guide It consists of a guide 1 and a crab-eye pin 2, and this guide 1 is connected to the screw 5 to be turned. come together. The crab eye pin 2 is inserted into the screw hole 6. This ensures work safety I can do it. Also, it can be used in combination with crab eye socket 3 and ratchet handle 4. By doing this, the crab eye pin 2 and ratchet handle 4 can work at a free phase angle. This allows you to work easily even in tight spaces.

[0008] In addition, the crab eye pin 2 and ratchet handle 4 allow work at any angle. Therefore, when working in an environment with an infinite rotation range, the ratchet can be adjusted without rotating the handle 7 many times. Utilizing the characteristics of the cut handle 4, the screw 5 can be tightened and loosened.

[0009]

[Effect of the idea]

According to the present invention, the angle of rotation of the handle is limited by this cranioid wrench. It is also effective in reducing work time and improving safety in the environment.
